Keyboard Key Structure with Hook-Driven Detachable Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing keyboard key structures are difficult to repair and clean, leading to reduced service life, and require tools for hook engagement and disengagement.
Innovation Solution
A key structure comprising a base with a structural plate and connecting plate, a keycap with a first hook, and a connecting rod with a second hook, allowing the keycap to be easily fastened or detached from the connecting rod by moving it along an extension direction, facilitating cleaning and repair without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the keycap is firmly fixed to the base using hooks, then the structural stability is improved, but the ease of repair and cleaning deteriorates
Solution Approach 1:
The key structure is divided into separable components: the keycap with first hook, the connecting rod with second hook, and the base. The hooks are designed as independent fastening elements that can be engaged or disengaged independently, allowing the keycap to be separated from the base for cleaning and repair while maintaining structural stability during normal use.
Solution Approach 2:
The connecting rod is designed to be movable along the extension direction relative to the base. This dynamic capability allows the connecting rod to be pushed to disengage the second hook from the first hook, enabling easy removal of the keycap for cleaning and repair, while maintaining firm fixation during normal operation.
2Stability of the object's composition
If traditional fastening methods are used for the keycap, then the structural stability is improved, but the ease of operation deteriorates due to requiring additional tools
Solution Approach 1:
The hook mechanism is designed to be self-operating. The connecting rod itself serves as the tool for disengagement - by pushing the connecting rod along the extension direction, the second hook is automatically disengaged from the first hook. This eliminates the need for additional tools while maintaining secure fastening during normal use.
3Duration of action of stationary object
If the keycap is permanently attached to the base, then the service life is improved through continuous stability, but the ease of repair deteriorates
Solution Approach 1:
The key structure is segmented into removable components connected by hooks. The keycap with first hook can be separated from the base by disengaging the hooks through pushing the connecting rod. This allows periodic cleaning and repair to extend service life, while maintaining stable attachment during normal operation.
Solution Approach 2:
The connecting rod's movability along the extension direction provides a dynamic mechanism for easy disengagement. By pushing the connecting rod, the second hook disengages from the first hook, enabling keycap removal for cleaning and repair, thereby extending the overall service life of the key structure.

AI summary
A key structure includes a base, a keycap, and a connecting rod. The base includes a structural plate and a connecting plate. The connecting plate is configured on the structural plate. The keycap is configured on the structural plate and includes a plate body and a first hook. The connecting rod is configured under the structural plate and extending towards an extension direction. The connecting rod includes at least a second hook. The connecting rod moves along the extension direction relative to the base to drive the second hook to be fastened to or detached from the first hook. When the first hook is detached from the second hook, the keycap moves relative to the connecting rod to expose the space between the keycap and the base, and then the key structure is easily repaired or cleaned.
